Privacy Policy

This Privacy Policy explains how Mài Sắt Mindset ("we", "us", or "the platform"), which operates the website maisatmindset.com, collects, uses, and protects your information when you use our educational website and services.

1. Information we collect

• Account information — your name, email address, and password (stored in encrypted/hashed form). If you are a teacher, your account may also hold classroom details.
• Learning data — your activity on the platform, such as lessons and articles you read, reading progress, answers and quiz results, spaced-review schedules, and vocabulary or flashcard practice. We use this to save your progress and personalize your learning.
• Communications — messages you send us (for example, support requests).
• Technical data — collected automatically to operate and secure the site, including session/cookie data, approximate IP address, browser and device type, and pages visited.

2. How we use your information

• To provide and maintain the service and your account.
• To save your learning progress and personalize your experience.
• To send essential transactional emails (such as email verification, password resets, and class or enrollment notices).
• To keep the platform secure and prevent abuse.
• To understand how the platform is used so we can improve it.

We do not sell your personal information, and we do not use it for third-party advertising.

3. Cookies

We use essential cookies to keep you signed in and to remember preferences such as your chosen language and light/dark theme. We do not use advertising or cross-site tracking cookies.

4. Service providers

We rely on a small number of trusted providers that process data on our behalf, only as needed to run the platform:

• Google (Gemini API) — to generate and translate learning content and to grade practice. Text submitted for these features may be processed by Google.
• Resend — to deliver transactional emails.
• Our hosting and infrastructure providers — to store data and serve the website.

5. Children's privacy

The platform is designed for both young learners and adults. Accounts for children should be created and supervised by a parent, guardian, or teacher. We collect only the information needed to provide the learning service and do not knowingly collect unnecessary personal information from children. If you believe a child has provided us personal information without appropriate consent, please contact us and we will delete it.

6. Data retention and security

We keep your information for as long as your account is active or as needed to provide the service. Passwords are stored hashed, and we apply reasonable technical and organizational measures to protect your data. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

7. Your rights

You can access and update your account information from your account settings, or request a copy or deletion of your data by contacting us. We will respond to reasonable requests in line with applicable law.

8. International users

Your information may be processed in countries other than your own. By using the platform, you consent to this processing.

9. Changes to this policy

We may update this Privacy Policy from time to time. When we do, we will post the revised version on this page and update the date above.
